The mesoporous material having a large surface area and pore volume, and a controllable pore size, narrow pore size distribution and other characteristics, and thus has a wide range of potential applications, such as adsorption, separation, catalysis, drug delivery, photonic and electronic equipment. Pure silica mesoporous materials lack the active center, poor thermal stability, so that the application subject to certain restrictions. Thus, the hetero atom is introduced in the mesoporous materials of the pure silicon to enhance its activity in an important way. Among them, Al doped modified mesoporous materials (such as Al-MCM-41, Al-SBA-15) has a more acidic centers, better hydrothermal stability by the academic attention. With respect to the Al-MCM-41 mesoporous materials, Al-SBA-15 easier synthesis, and having a larger pore size, the more a thickness of the hole wall and better hydrothermal stability, and therefore more suitable for the catalytic reaction substrate as the macromolecules reactions. The other hand, 2,4 - di-t-butyl phenol, and cinnamyl alcohol Friedel alkylation reaction occurs, the generated styrylphenyl phenolic compound is an important intermediate in organic synthesis, with ethylene oxide, amino sulfonic acid and other substances react and generate a series of compounds, these products are widely used in the field of chemicals, pesticides, and other. Al-SBA-15 in the alkylation reaction of Friedel better catalytic activity and therefore the study Al-SBA-15 2,4 - di-tert-butyl phenol and cinnamyl alcohol Friedel alkylation reaction have important practical significance and academic value. This thesis triblock copolymer P123 as template and TEOS as silica source, aluminum isopropoxide, aluminum chloride, aluminum source, direct hydrothermal synthesis prepared by Al-SBA-15 mediated porous materials by means of XRD, N2 adsorption - desorption, TEM, SEM, FT-IR, NH3-TPD, ICP and Py-IR and other means were used to characterize its structure and composition, and 2,4 - di-tert-butyl catalytic performance in the alkylation reaction of phenol and cinnamyl alcohol were more detailed investigated many factors that affect its structure and performance of the synthesis process, under the conditions of this thesis, the main conclusions are as follows: 1. isopropyl aluminum alcoholate Al-SBA-15 mesoporous materials were synthesized as aluminum source: the the crystallization precursor solution thermostatic 40 ° C, the cast compound Si / Al molar ratio of the sample was prepared under the conditions of 40,110 ° C crystallization 2d structural integrity catalytic performance. Synthesis of Al-SBA-15 mesoporous materials 2. Aluminum chloride as the aluminum source: the crystallization of the precursor solution heated 40 ° C, cast Si / Al molar ratio of compound 2d under conditions of 50,110 ° C crystallization of the prepared samples having the most good mesoporous structure; catalytic performance evaluation results show that under the same conditions, the cast compound the Si / Al molar ratio of 40 samples showed the best catalytic performance. Prepared by the comparison of the two aluminum source on Al-SBA-15 sample structure and catalytic activity differences, found that the catalytic activity of aluminum isopropoxide as aluminum source synthesis of mesoporous materials better, while the aluminum chloride Al doping as aluminum source prepared sample crystalline phase and preferably the mesoporous structure, which is mainly derived from the silicon source and aluminum source, the hydrolysis rate matching differences and the preparation process due to the acidity of the solution was different impact effect, thereby affecting its structure and catalytic properties.
